ROBERT B. OISSEL, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO BACKUS WATER MOTOR COMPANY, OF NEWARK, NEW

JERSEY, A CORPORATION OF NEW JERSEY.

. GAS-PPRODUCER.

Eatented. Feb. 18, 1908.

To all whom it may concern:

Be it known that 1, ROBERT B. CissEL, a

. citizen of the United States, residing in Elizabeth, county of Union, State of New Jersey, have invented certain Improvements in Gas- Producers for Supplying Internal-Combustion Engines, of which the following is a specification.

' taken immediately above pit is opper B. The

This invention is designed to afford an efliciently acting gas producer of moderate size and OfCOIlVGIliIlt and economical con struction that will produce a substantially uniform quality ofnon-carbureted producer gasfor fuel supply of internal combustion engines.

The details of construction are hereinafter set forth.

In the accompanying drawing: Figure 1 is a vertical section through the apparatus: Fig. 2, a horizontal section through Fig. l the grate, and Fig. 3, a detail perspective View of the air and'aqueous vapor supply device located symmetrically beneath the grate.

The producer A comprising the usual shell, refractory brick lined fuel chamber and ash provided with the usual fuel charging producer is shown square in horizontal cross section. At the base of the brick work there is at each corner (or at four equi-distant points) left a recess Ct in which is secured a bracket ato the horizontal arm of which is applied a chain a These four pendent chains support two parallel end bars 0 of a rectangular grate of any appropriate construction, and one of which'has a suitable stud, or an aperture 0 for thereception of a shaker. The swinging oscillatory motion imparted to the suspended grate acts sufficlently to clear the base of the fuel column.-

D indicates a pipe or connection for the introduction of an air blast to blow up the fuel. Products of combustion, or gases prothrough a somewhat elongated chamber shown as a cylindrical drum F and then downward to a water sea G at the bottom of an ordinary washer through which the gaseous products rise and pass out through the pipe H. Water sup plied through pipe 1 passes through a su ply regulating valve i to a drip nozzle iwlilch delivers water to the receiving funnel perforated pipe I arranged above the flue in the vaporizer or drum F, which is provided with a slide valve f for admission of regulated quantities of air. From the bottom of the drum, the air, mixed with the aqueousivapor created by the heat of flue E, and such water as may not be vaporized descends through pipe J which-enters the ash pit and communicates with a hollow ring K symmetrically disposed beneath the grate. This trance of ashes.

As seen in Fig. 3, the capacity of ring K below the level of the to contain a substantia Should there be a surp overflow into the ash pit from which it may be withdrawn if desired. This volume of Water, under. the temperature present in the ash pit, continuously throws oif va or which with that supplied through pipe J is drawn upwardly through the fuel in the producer the usual reactions occurring for the production of so-called producer or water-gas. The special construction of the vapor supply ring beneath the grate indicated in the drawing has been shown by experience to be highly efficient. The ring is composed of a section of pipe and the apertures are formed in its side by transverse slits connected at the bottom by a horizontal slit, the flap of metal thus formed being turned outwardly some what, as shown. strated that a vapor device havin the charl acteristics of that described an provide with equidistant exit apertures for the aque ous vapor and having the capacity of retaining surplus water is highly efficient in this class of apparatus since the vapor is supplied with a very substantial degree of uniformity with reference to the bottom of the fuel column. The vapor supply device K has quantity of water.

brick lining, as is usual in this class of ap aratus, is so built in as to afford a fuel chamlier circular in cross section.

I claim:

1. A producer having a grate in its lower portion and an aqueous vapor supply device consisting of a hollow ring symmetric-ally dis posed beneath the grate and having in its side substantially equidistant apertures extendthe admission of ashesto the ring and to l facilitate the passage of ashes from the top I of the ring.

apertures 7c is such as,

Experience has demonbeen shown as circular since the refractory.

ing downwardly along the sides provided with downwardly inclined hoods to prevent ring is formed with apertures 7c in its side which are protected by hoods 1c against enlus, it will merely 2. A producer-provided with a, grate and having a. vapor supply device located beneath the grate composed of a continuous hollow horizontally arranged body having a curved top and provided with apertures extending downwardly along the sides but terminating above the bottom of the vapor sn ply device which are protected by lateral y projecting downwardly extending hoods and which have s ace beneath the level of the apertures for lolding a substantial quantity of water.

In testimony whereof, I have hereunto subscribed my name.
